Hi ,
I am trying to enable iscsi multipath on Solaris 10 Update 3 using
mpxio which is shown as supported on netapp support matrix.
We have made following on the system to enable iscsi+mpxio
pkgadd -d NTAPSANTool.pkg
cd /opt/NTAP/SANToolkit/
./mpxio_set -e
reboot -- -r
Our netapp IP address is 192.168.199.31 and 192.168.199.32. I have
used following commands on Solaris
iscsiadm add discovery-address 192.168.199.31:3260 (adding first head of netapp)
iscsiadm add discovery-address 192.168.199.32:3260 (adding second head
of netapp)
iscsiadm modify discovery --sendtargets enable
/opt/NTAP/SANToolkit/bin/sanlun lun show all shows
filer: lun-pathname device
filename adapter protocol lun size
lun state
btelnetapp2: /vol/iscsisolaris/data/iscsilun1
/dev/rdsk/c2t60A98000572D43354E4A524249686F6Cd0s2 iscsi0 iSCSI
40.0g (42953867264) GOOD
iscsiadm list target command gives following output:

After that we use commands listed
http://docs.sun.com/app/docs/doc/817-5093/gcawf?a=view
iscsiadm modify initiator-node -c 2
iscsiadm modify target-param -c 2 iqn.1992-08.com.netapp:sn.151701367
iscsiadm modify target-param -c 192.168.199.32,192.168.199.31
iqn.1992-08.com.netapp:sn.151701367
While issuing those commands we get following errors:

Error 145 states that there is a network problem but we have connected
a windows machine on the same switch using same cable but we live no
problem and performance is well.
My questions are:
1) What is the best practice to use Solaris10 mpxio+iscsi
2) Why we get above errors? Maybe I must change default values for
target (netapp). Anyone here in this list have experience for that?
